Chiral property of domain-wall fermion from eigenvalues of 4D Wilson-Dirac Operator
نویسندگان
چکیده
We investigate a chiral property of the domain-wall fermion (DWF) system using the four-dimensional hermitian Wilson-Dirac operator HW . A formula expressing the Ward-Takahashi identity quark mass m5q with eigenvalues of this operator is derived, which well explains the N5 dependence of m5q observed in previous numerical simulations. We further discuss the chiral property of DWF in the large volume in terms of the spectra of HW .

We investigate chiral properties of the domain-wall fermion (DWF) system by using the four-dimensional hermitian Wilson-Dirac operator. We first derive a formula which connects a chiral symmetry breaking term in the five dimensional DWF Ward-Takahashi identity with the four dimensional Wilson-Dirac operator, and simplify the formula in terms of only the eigenvalues of the operator , using an an...

متن کاملLow energy effective action of domain-wall fermion and the Ginsparg-Wilson relation
We derive the effective action of the light fermion field of the domain-wall fermion, which is referred as q(x) by Furman and Shamir. The inverse of the effective Dirac operator turns out to be identical to the inverse of the truncated overlap Dirac operator, except a local contact term which would give the chiral symmetry breaking in the Ginsparg-Wilson relation. This result allows us to relat...

Chiral properties of QCD formulated with the domain-wall fermion (DWQCD) are studied using the anomalous quark mass m5q and the spectrum of the 4-dimensional Wilson-Dirac operator. Numerical simulations are made with the standard plaquette gauge action and a renormalization-group improved gauge action. Results are reported on the density of zero eigenvalue obtained with the accumulation method,...

We describe a way to optimize the chiral behavior of Wilson-type lattice fermion actions by studying the low energy real eigenmodes of the Dirac operator. We find a candidate action, the clover action with fat links with a tuned clover term. The action shows good scaling behavior at Wilson gauge coupling β = 5.7. There is an increasing accumulation of evidence from lattice simulations that the ...
